GASOLENE-FILTER.

Application filed April 28,

To all whom it may concern:

Be it known that I, J on ELLIs, a citizen of the United States, residing at Lynn, in the county, of Essex and State of Massachusetts, have invented new and useful Improvements in Gasolene-Filt1ers, of which the following is a specification.

This invention relatesto an improved filter and separator particularly adapted to be the purpose hereinbefore set forth which can readily be inserted in the pipe leading from the gasolenc tank to the carbureter.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a side elevation of my improved filter and separator with a portion of the pipes which connect the filter with the tank and with the carburcter shown attached thereto and broken off to save space. Fig. 2 is a longitudinal central section, partly in elevation of said device. Fig. 3 is a-section, partly in elevation, taken on line 3 3 of Fig. 2, looking toward the left in said figure. Fig. 4 is a side elevation of the plug or drip cock by means of which water is allowed to pass out of the'watcr cham ber.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 6 is a casing having a passageway 7.extending longitudinally therethrough with a cap 8 at one end thereof and a cap 9. at the other end thereof. The caps 8 and 9 have screw-threaded engagement with the casing 6 and the leakage of gasolene is prevented by means of gaskets or washers 10. The caps 8 and 9 each have a passage 11 and 12, respectively, extending therethrough constituting inlet and outlet orifices, respectively. The ipe' 13 has screw-threaded engagement with the cap 8 and leads to the gasolene tank; the pipe 14 has screw-threaded engagement with the cap 9 and leads to the carbureter.

Adjacent to the inlet passage 11 is a filter Specification 6r Letters Patent.

chamber 15 located in the passageway 7, the filter consisting, preferably, of strainers 16 and 17 with a filtering substaprc 18 of any desirable material introduced between saidv strainers.

The filtering material 1% may be either quartz, carbon, charcoal, or washers of felt may be'used as may be desired. Beneath the passageway 7 and between the filtering chamber 15 and the outlet orifice 12 is a precipitation chamber 19 which is of sutliciently greater area than the inlet and outlet pas sages, to afford, in a sense by retardation, an expansion or precipitation chamber, ':.'hcrein, be ore passage of the gasolene through the outlet, the water carried thereby will settle or precipitate, the gasolenc passing on through the outlet. A projection 20 is provided beneath this chamber 19 which is interiorly screw-threaded to engage a plug 21. The plug 21 constitutes a drip-cock or valve, its upper face bearing against a valve-seat 22 adjacent to a passage 01' port 23 leading downwardly from the interior of the precipitation chamber 19. The upper portion of the plu 21 is reduced in diameter at 24 and 'has a cross-passage 25 thereinwhich connects with a vertical passage 26 leading downwardly and through the lower end of the plug 21.

i The operation of the device hereinbefore specifically described is as follows: Gasolene passes through the pipe 13 from the gasolene tank and. through the inlet passage or orifice 11 to the interior of the casing 6. Said gasolene passes through the strainer 17, then through the filtering material 18, and through the strainer 16. During this portion of its passage any impurities or sediment \vhich may be contained therein are deposited upon the filtering material, and the gasolene thus filtered passes along through the passageway 7 and over the precipitation chamber 19. During this portion of its passage any water, which may be contained in its natural state in said gasolene drops, because of its greater specific gravity, to the bottom of the chamber 19, while the gasolene floats in the upper portion of said chamber and in' the passageway 7 until the chamber 19 has become filled with water, when it is drawn off by unscrewing to a slight extent the plug 21 and allowing the water to pass downwardlythrough the passage 23, around the reducedportion 24 of the plug 21 through the cross-passage 25- and downwardly through the outlet passage 26. The

- is placed 111 water separated therefrom passes through the outlet orifice or passage 12 into the pipe 14 and is conducted by said pipe to the cari bureter.

In a device of this character it is very es sential that the filtering material should be capable of being readily cleansed and also capable of being readily remoyed and new filtering material introduced in its lace. These ends are accomplished in the evice hereinbefore described in the following inanner: The impurities and sediment from the gasolene will be deposited in the filtering ma serial and upon and immediately adjacent to the outer strainer 17, and to remove these inipurities quickly and eificiently the device is etached from the pipes 13 and 14 and the cap 9 attached by a suitable fitting to a water faucet connected to a water supply under pressure. The water is then allowed to flow under pressure from the faucet through the filter and separator is the reverse direction to that indicated by the arrows in Fig. 2, whereupon'substantially all of the impurities I and sediment collected upon the filtering material and upoirthe strainer 17 will bel Washed therefrom outwardly through the passage 11 in the cap 8. l

The supply of filtering material can readily be introduced inrthe filtering chamber 15 by removing the s )lit spring 527 and the strainer 17 which is held in position by said spring, thus leavin the filter chamber open to remove any filtering material that may be con tained therein, and after thus removing the old filterin material new filtering material the filter chamber; and the the spring 27 replaced, as

gasolene having thus become filtered and the I strainer 17' with shown in Fig. 2.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:

1. A. gasolene filter and separator comprising in its construction a casing provided with a passageway extending longitudinally therethrough and having an inlet and an chamber adjacent to casing provided with a filter chamber adjacent to said inlet orifice, there being a precipitation chamber located beneath said passa eway between said filter and said outlet orince.

2. A gasolene filter and separator comprising in its construction a casing-provided with a passageway extending longitudinally therethrough having an inlet and an outlet orifice, said casing provided with a filter said inlet orifice, there precipitation chamber located beassageway between said filter l t orifice, and a drip-cock adapta passage leading out chamber.
